<b>Histopathological effects of repeated 14-day administration of rizatriptan benzoate in a nitroglycerin-induced migraine rabbit model</b>
...Show More Authors

Background: Migraine is one of multiple attack neurological conditions that causes moderate to severe headaches with no defined pathophysiology and few animal models. Aim: Establishing an animal model that reproduces migraine-like action is important in medical research to identify the mechanism underlying this disorder. Additionally, it facilitates the availability and reliability of new models that may act as human surrogate models. Method: Rabbits were divided into four groups. Negative group, migraine group, rizatriptan- nitroglycerin group, and rizatriptan group. The frequency of head scratching and the histopathological changes in the brain, liver, kidney, and heart for groups were evaluated in all groups. Results: The behavioral characteristic of head scratching was significantly increased in the NTG group (50.4±3.8) compared with the control group (9.2±1.3) after 30 min of the experiment. Moreover, animals treated with rizatriptan benzoate (Riza) 10 mg/kg/orally for 14 days followed by NTG injection showed a significant decrease in the head scratch action (16.8 ± 2.3 and 17.6±3.3) than the animals of NTG group (50.4±3.8 and 43.6±2.3) after 30 min and 60 min, respectively. Further, animals treated with Riza alone showed no statistical differences in the head scratches (7.8±1.3, 9.2±0.8, 10.6±1.1 and 9.6±1.3, respectively) during the 120 min of the experiment, compared with the control group. Histopathological alterations in the brain of rabbits that received NTG showed severe diffuse dilated and engorged blood vessels. These changes were also recorded in the liver and kidney of this group. This marked vasodilation of blood vessels and central and portal veins confirms the successful induction of migraine in the rabbit model. In contrast, animals treated with Riza for 14 days demonstrated substantially less vascular dilation following NTG injection. No significant pathological lesions were observed in animals treated with Riza. Conclusion: The current study successfully established a rabbit model of migraine using a single dose of NTG to induce migraine -like behavior. Moreover, pre-treatment with rizatriptan benzoate for fourteen days significantly reduced the symptoms of migraine and histopathological changes in different organs.

In this research want to make analysis for some indicators and it's classifications that related with the teaching process and the            scientific level for graduate studies in the university by using analysis of variance for ranked data for repeated measurements instead of the ordinary analysis of variance . We reach many conclusions  for the                         

important classifications for each indicator that has affected on   the teaching process.         &nb

Histopathological Changes caused by The Chronic Effect of Nitrofurantoin Drug in The Testes of Albino Mice
...Show More Authors

The present study was conducted to determine histopathological changes caused by chronic effect of Nitrofurantoin(NFT) in The albino mice Testes. The Study included 40 mice were divided on the five groups: the first group taken distilled water and become control group . the remaining group which are exposure with NFT drug in concentration (100-150-200-250) mg / kg, respectively, Doses were given orally for a period (month and two months). The results of histopathological changes included occurrence of congestion in the blood vessel and degeneration of spermatogonia and aggregation of spermatids in the lumen of semineferous tubules and inhibition of spermatogensis process and decrease of sperm inside the lumen

The Chinese vision of US rapprochement with Taiwan in the administration of President Joe Biden
...Show More Authors

The recent escalation in Southeast Asia showed that the region is on the verge of political and economic crises through the United States and its allies imposing economic sanctions against China, and a military escalation that may begin with China’s invasion of Taiwan, especially since two-thirds of the American forces in the world are located in the Taiwan Strait and the South China Sea.

The United States claims that it is ready to defend the island of Taiwan in the event of the start of Chinese military operations, but the reality shows that the United States supports Taiwan militarily by equipping it with modern weapons to defend itself. Supporting Taiwan economically by engaging it in trade agreements with US allies in the r

...Show More Authors

Epilepsy is considered as one of the common neurological disorders.About 50 million persons have affected by epilepsy .Carbamazepine is one of the common drugs used by pregnant women with epilepsy. The aim of the present study is to investigate the effect of carbamazepine on the process of brain development during day 13 of pregnancy.Fifty pregnant albino mice have been used. They were divided into two groups. The control group that had been orally drenched with normal saline. The other group was treated group that had been given 15 mgKg of Carbamazepine orally. The fetuses have been collected after killing of the mice. Boun’s solution was selected as fixative. 5-8 µm thick sections from the fetuses were cut to be stained with hematoxyli
